Discovery of Nitrogen, by Caleb

Today in the Mystery of the Periodic Table, I read about how they separated  oxygen from the other gas, but what was the other gas? A mouse could not breathe in it. It tasted weird, and so they decided it was part of the recipe for the air we breathe, and that phlogiston was just a theory and that when a candle went out under a jar it was cause there was no oxygen, there was only nitrogen left which was the weird gas, and cause there was just nitrogen left that proved there was no phlogiston.

Benjamin Franklin, by Grace

Benjamin Franklin was born in the winter of 1706 in Boston Massachusetts. He came into a family of 16! (Probably where he learned how to get along with people)
Ben was his father's favorite. At five, he could read the Bible. And we'll started thinking seriously when he was 7. One time asked his father, (Josiah) " why waste all this time giving your daily blessing? Why not give one blessing once and for all? I think this would save your time and the Lord's time."
Josiah thought he would make a good clergy man. So he sent him to Boston Latin School for a classical education. But he soon realized that was not for his son. So he transferred him to another school, but it was too expensive when there were 17 mouths to feed. So Ben was offered to be a candle maker but he couldn't stand the smell of tallow. So he found himself age 12, an apprentice his brother's printing shop. He stopped going to church and would stay home and read a good book. He said that a good book more educational then a bad sermon. But he still had a deep reverence for God.
When Ben was 17 he found he couldn't get along with his brother, so snuck away on a boat. He landed in Philadelphia. He was very ragged and had only one dutch dollar. He worked as a printer. Soon he had his own printing shop. He was a very smart man, and besides inventing the lighting rod and finding out what electricity is he was a great founding father. He got France to join us in a critical part of the war, he had the wisest of mind for starting our country. He deserves the love and thanks of man and women.

The Discovery of Oxygen, by Caleb

On August 1st 1774 Priestly put calx of Mercury underneath a glass and it began to give off a gas. The gas was oxygen. Well, this gas was very flammable and he wondered if it was poison so he took a jar and filled it with air then he took another jar with this gas and put a mouse in each one. The mouse with the weird gas lived for 30 minutes but the one with normal air lived half that long. The air we breathe is only 20% oxygen.

Mr Priestly was saying that the reason that when you put a candle in a jar and it goes out is because it puts off phlogiston, but really it just uses up the oxygen.

Later, Lavoisier did an experiment that proved it was burning up all the oxygen, and not really just filling the jar with phlogiston.

Priestly discovered the mysterious unknown gas, but Lavoisier is the one who proved it to be the oxygen we breathe. He also proved the Priestly was backward in his science.

Dr. Joseph Warren, by Lucy

Joseph Warren, by Copely

Dr. Joseph Warren (June 11, 1741 – June 17, 1775) was an American Physician and a valiant patriot. They all loved him. Dr Warren was made a general on June 14, 1775 and was killed at the Battle of Bunker Hill (June 17, 1775).

Dr Warren was a part of two battles. The Battle of Lexington and Concord and the Battle of Bunker Hill. He was a great leader and supported his troops.

Robert Boyle, by Caleb

Today, in Mystery of the Periodic Table, I read about Robert Boyle who was the 14^th child. His father was an earl and was very rich. He was about 15 when he started his experiments and Galileo died just that year.

Although there were a lot of kids in his family, he inherited a lot of money but he did not waste it. He used it for experiments and for his lab.
